Use pure hydraulic oil on Zetor 6245 ?

I bought the tractor 2 years ago. former owner have used pure hydraulic oil on the transmission. He used Statoil hydraway HVXA 32 on the transmission. Is it posibilty to use this kind of oil on the hydraulic/transmission ??

Hydraulic oil doesnt have the additives that improve the hydrodynamic film buildup between high pressure gear contact. Its cheaper than UTTO because its a lesser product. Its not suitable to lubricate transmissions. Better than water though...

Ok. So i need to drain the Whole system With the loader. Wich is the best way to drain it, so i get most of the hydroil out ???

I will replase it With SAE 80W-90, API GL-5 Hypogearoil .

If you drain the transmission, 70% of the hydraulic fluid will be out of the system. When mixing the last few liters of VG 46 hydraulic oil with 80w/90 gear oil, UTTO is more or less what you get (an oil with additives for both gear lubrication and anti-foam additives for hydraulic systems)

So dont worry about getting the last 5 liters out. It will mix just fine.
